An enterprise application targets a particular business domain, usually having a GUI for multiple concurrent users and an application database for many entity types; also, it often integrates with other applications inside or outside the organization. In Java, the Java EE APIs and/or the Spring framework are typically used when building such applications.
In this chapter we describe an approach to test Java enterprise applications by writing out-of-container integration tests, where each test exercises a single step in a well-defined business scenario (also known as a "use case" or "usage" scenario). With a typical layered architecture, such a test calls a public method from a component in the highest layer (normally, the application layer), which then calls down to lower layers.
For demonstration, we will use a Java EE version of the Spring Pet Clinic sample application. The full code is available in the project repository. The application codebase is organized in four layers: UI or presentation layer, application layer, domain layer, and infrastructure layer.
The application's domain model (following the approach and terminology of
Domain Driven Design) has six domain
entities: Vet
(a veterinarian), Specialty
(a vet's specialty), Pet
, PetType
,
Owner
(a pet's owner), and Visit
(a visit from a pet and its owner to the clinic).
Besides entities, the domain model (and layer) of the application also includes domain service classes.
In this simple domain, we have only one such class for each entity type (VetMaintenance
, PetMaintenance
, and
so on).
In DDD, entities are added into and reconstituted or removed from persistent storage through "repository" components.
Given that we use a sophisticated ORM API (JPA), there is only one such repository, which is not domain or application specific and
therefore goes into the infrastructure layer: the Database
class.
The application uses a relational database, specifically an in-memory HSqlDb database in the sample application, so that it can be
self-contained.
The application layer contains application service classes, which translate user input from the UI to calls into the lower layers, and make output data available for display in the UI. This is the layer at which database transactions are demarcated.
With Java EE 7, we use JPA for the domain @Entity
types, EJBs (stateless session beans) or simply
@Transactional
classes for domain services, and JSF @ViewScoped
beans for
the application services.
Code for the UI layer is not included in the sample, as it wouldn't be exercised by the integration test suite anyway.
(In Java EE, this layer would be comprised of JSF facelets in the form of ".xhtml" files.)
For our first integration test class, let's consider the Vet screen, which simply displays a list of all vets with their specialties.
public final class VetScreenTest
{
@TestUtil VetData vetData;
@SUT VetScreen vetScreen;
@Test
public void findVets() {
// Inserts input data (instances of Vet and Specialty) into the database.
Vet vet2 = vetData.create("Helen Leary", "radiology");
Vet vet0 = vetData.create("James Carter");
Vet vet1 = vetData.create("Linda Douglas", "surgery", "dentistry");
List<Vet> vetsInOrderOfLastName = asList(vet0, vet1, vet2);
// Exercises the code under test (VetScreen, VetMaintenance, Vet, Specialty).
vetScreen.showVetList();
List<Vet> vets = vetScreen.getVets();
// Verifies the output is as expected.
vets.retainAll(vetsInOrderOfLastName);
assertEquals(vetsInOrderOfLastName, vets); // checks the contents and ordering of the list
Vet vetWithSpecialties = vets.get(1); // this will be "vet1"...
assertEquals(2, vetWithSpecialties.getNrOfSpecialties()); // ...which we know has two specialties
vetData.refresh(vetWithSpecialties); // ensures the Vet contains data actually in the db
List<Specialty> specialtiesInOrderOfName = vetWithSpecialties.getSpecialties();
assertEquals("dentistry", specialtiesInOrderOfName.get(0).getName()); // checks that specialties...
assertEquals("surgery", specialtiesInOrderOfName.get(1).getName()); // ...are in the correct order
}
}
The first thing to notice in the test above is that it starts at the topmost layer of the application, which is coded in Java and therefore runs entirely in the JVM: the application layer. So, the test is not concerned with any HTTP requests and responses, or how application URLs map to components in the application layer; such details vary with the technology used for UI implementation (JSF, JSP, Struts, GWT, Spring MVC, etc.), and are considered out of the scope of the integration tests.
The second thing to notice is the test code is very clean and focused on what it's trying to test. It's written entirely in terms of the application and its business domain, without low-level concerns such as deployment, database configuration, or transactions.
Finally, the third thing to notice is that no JMockit API at all appears in the test class.
All we have is the use of the @TestUtil
and @SUT
annotations.
These are user-defined annotations, with arbitrary names chosen according to the preferences of the team.
In our sample code, they are defined as follows.
@Target(ElementType.FIELD)
@Retention(RetentionPolicy.RUNTIME)
@Tested(availableDuringSetup = true, fullyInitialized = true)
public @interface TestUtil {} // a test utility object
@Target(ElementType.FIELD)
@Retention(RetentionPolicy.RUNTIME)
@Tested(fullyInitialized = true)
public @interface SUT {} // the System Under Test
So, here we use JMockit's @Tested
annotation as a meta-annotation.
The use of "fullyInitialized = true
" causes the dependencies of a tested class to be automatically resolved through
dependency injection (specifically, constructor injection followed by field injection, as applicable).
The use of "availableDuringSetup = true
" merely causes the tested object to be created before any test setup
methods (@Before
in JUnit or @BeforeMethod
in TestNG) are executed,
contrary to the default which is to create tested objects right before each test method executes, and after any setup methods.
In this first example test class, this effect is not used, so the only benefit of using "@TestUtil
" is to
document the intent of the field in the test class.
As seen in the test, VetData
provides methods that create new test data needed by the test, and other utility
methods such as refresh(an entity)
(which forces the persistent state of a given entity to be freshly loaded from the
database).
As the name implies, the test suite would have one such class for each entity type, to be used in one or more test classes whenever they
need persistent instances of said types.
More details are provided in the following section.
Utility classes like VetData
look like the following.
public final class VetData extends TestDatabase
{
public Vet create(String fullName, String... specialtyNames) {
String[] names = fullName.split(" ");
Vet vet = new Vet();
vet.setFirstName(names[0]);
vet.setLastName(names[names.length - 1]);
for (String specialtyName : specialtyNames) {
Specialty specialty = new Specialty();
specialty.setName(specialtyName);
vet.getSpecialties().add(specialty);
}
db.save(vet);
return vet;
}
// other "create" methods taking different data items, if needed
}
Such classes are easy to write, as they simply use the existing entity classes, plus the methods made available in a "db
"
field from the TestDatabase
base class.
This is a test infrastructure class which can be reused for different enterprise applications, as long as they use JPA for persistence
(and JMockit for integration testing).
public class TestDatabase
{
@PersistenceContext private EntityManager em;
@Inject protected Database db;
@PostConstruct
private void beginTransactionIfNotYet() {
EntityTransaction transaction = em.getTransaction();
if (!transaction.isActive()) {
transaction.begin();
}
}
@PreDestroy
private void endTransactionWithRollbackIfStillActive() {
EntityTransaction transaction = em.getTransaction();
if (transaction.isActive()) {
transaction.rollback();
}
}
// Other utility methods: "refresh", "findOne", "assertCreated", etc.
}
The Database
utility class (also available and used in production code) provides an easier to use API than
JPA's EntityManager
, but its use is optional; tests could directly use the "em
" field instead of
"db
" (were it made protected
, of course).
The EntityManager em
field in the test database class gets injected with an instance automatically created according to the
META-INF/persistence.xml
file that should be present in the test runtime classpath (this would go into the "src/test"
directory when using a Maven-compatible project structure; a "production" version of the file can then be provided under "src/main").
A single default entity manager instance is created, and injected into whichever test or production classes (such as the
Database
class) have a @PersistenceContext
field.
If multiple databases are needed, each would have a different entity manager, as configured by the optional "name
" attribute
of this annotation, with the corresponding entry in the persistence.xml
file.
Another important responsibility of this base class is to demarcate the transaction in which each test runs, ensuring that it exists
before the test begins, and that it ends with a rollback after the test is completed (either with success or failure).
This works because JMockit executes the @PostConstruct
and @PreDestroy
methods (from the standard javax.annotation
API, also supported by the Spring framework) at the appropriate times.
Since each "test data" object is introduced to the test class in a @Tested(availableDuringSetup = true)
field, it gets "constructed" before any setup or test method, and "destroyed" after each test is finished.
Spring-specific annotations such as @Autowired
and @Value
are also
supported in fully initialized @Tested
objects.
However, a Spring-based application can also make direct calls to BeanFactory#getBean(...)
methods, on instances of various
BeanFactory
implementation classes.
Regardless of how said bean factory instances are obtained, @Tested
and
@Injectable
objects can be made available as beans from the bean factory instance, by simply applying the
mockit.integration.springframework.FakeBeanFactory
fake class, as shown below using JUnit.
public final class ExampleSpringIntegrationTest
{
@BeforeClass
public static void applySpringIntegration() {
new FakeBeanFactory();
}
@Tested DependencyImpl dependency;
@Tested(fullyInitialized = true) ExampleService exampleService;
@Test
public void exerciseApplicationCodeWhichLooksUpBeansThroughABeanFactory() {
// In code under test:
BeanFactory beanFactory = new DefaultListableBeanFactory();
ExampleService service = (ExampleService) beanFactory.getBean("exampleService");
Dependency dep = service.getDependency();
...
assertSame(exampleService, service);
assertSame(dependency, dep);
}
}
With the bean factory fake applied, a tested object from a field in the test class will be automatically returned from any
getBean(String)
call on any Spring bean factory instance, provided the given bean name equals the tested field name.
Additionally, the mockit.integration.springframework.TestWebApplicationContext
class can be used as a
org.springframework.web.context.ConfigurableWebApplicationContext
implementation which exposes
@Tested
objects from test classes.
Some application codebases use separate Java interfaces for many of their application-specific implementation classes.
These interfaces, then, are the ones used in the fields and/or parameters that receive injected dependencies.
So, when instantiating a @Tested
object having interface-based dependencies, JMockit needs to be told
about the classes implementing those interfaces.
There are two ways to do this.
In this testing approach, the goal is to have integration tests covering all of the Java code in the codebase of an enterprise application. To avoid the difficulties inherent to having the code run inside a Java application server (such as Tomcat, Glassfish, or JBoss Wildfly), these are out-of-container tests where all code (production as well as test code) runs in the same JVM instance.
The tests are written against the API of the highest-level components of the application. Therefore, UI code is not exercised, as it's typically not written in the Java language, but in a technology-specific templating language such as JSF facelets, JSPs, or something supported by the Spring framework. To exercise such UI components, which in a web application also often include JavaScript code, we would need to write functional UI tests based on HTTP requests and responses, using a testing API such as WebDriver or HtmlUnit. Such tests require an in-container approach, which brings a host of practical problems and difficulties, such as how/when to start the application server, how to deploy/re-deploy the application code, and how to keep tests isolated from each other given that a typical functional test often performs one or more database transactions, some or all of them usually getting committed.
In comparison, the out-of-container integration tests shown here are more fine grained, typically comprising a single transaction which is always rolled back at the end of the test. This approach allows for tests that are easier to create, faster to run (in particular, with negligible startup cost), and much less fragile. It's also easier to employ a code coverage tool and easier/faster to use a debugger, since everything runs in a single JVM instance. The downside is that code in UI templates, as well as client-side JavaScript code, doesn't get covered by such tests.


Liverpool squad confirmed for Aston Villa trip as Jurgen Klopp faces midfield dilemma
Jurgen Klopp's men take on Aston Villa in the Midlands on Saturday, looking to remain top of the table
by Alex Richards, https://www.facebook.com/AARichards/Jurgen Klopp has decisions to make when Liverpool face Aston Villa in the Premier League on Saturday - not least whether to risk Fabinho in midfield.
The Brazilian is one booking away from a suspension, and if he sees yellow against the Villans will miss the top of the table showdown with champions Manchester City next weekend.
Asked how he would deal with his problem, Klopp joked on Friday: "No challenges at all.
"[But] It's not possible against Aston Villa, playing without challenges in that position. You cannot ask for this. Player knows it, I know it."
As such, he must decide whether to keep the Monaco man at the base of midfield, or drop captain Jordan Henderson into the deeper role.
Liverpool will decide late over whether Naby Keita is fit to play, having been substituted in midweek due to injury.
The Reds remain without long-term absentee Nathaniel Clyne and Xherdan Shaqiri, who continues to have a calf problem.
Joel Matip is out for "a few weeks" with a knee issue and young defender Ki-Jana Hoever is at the Under-17 World Cup also.
For Villa, Dean Smith is expected to recall Jack Grealish to his starting lineup, after the captain missed the midweek Carabao Cup win over Wolves .
Grealish suffered a calf injury at Manchester City last weekend but Smith admitted: “Jack is OK, he’s pushing to be fit for Saturday. He’s responded really well to treatment.
“He’s getting there. I am very, very hopeful that he will be fit for the weekend.”
Liverpool squad
Goalkeepers: Alisson Becker, Adrian.
Defenders: Trent Alexander-Arnold, Joe Gomez, Virgil van Dijk, Dejan Lovren, Andrew Robertson
Midfielders: Fabinho, Jordan Henderson, Alex Oxlade-Chamberlain, James Milner, Gini Wijnaldum, Adam Lallana, Naby Keita
Forwards: Mo Salah, Roberto Firmino, Divock Origi, Sadio Mane, Rhian Brewster


Woman, 95, dies in dog attack at home of animal activist
by EndPlaySUFFIELD, Conn. (AP) - A 95-year-old Connecticut woman has died from injuries she suffered when she was attacked by a dog at the home of a former lawmaker who is also an animal rights activist.
Authorities say Janet D'Aleo, of Enfield, was found with life-threatening injuries Wednesday and brought to a Massachusetts hospital.
Police say D'Aleo was visiting a home in Suffield when she was bitten. The address disclosed by police is the same address as the home of animal rights activist and former state Rep. Annie Hornish.
Authorities say the 4-year-old male pit bull and pointer mix has been quarantined, pending further investigation.
Suffield Police Chief Richard Brown says officers will investigate the dog's background and what prompted the attack.
He says the Hornish family had the dog for several months and police hadn't received any complaints.

London crowd disrespectful towards Djokovic - tennis pundits
Cape Town - Tennis pundits Annabel Croft and Greg Rusedski have come out in support of Novak Djokovic after seeing the O2 Arena crowd cheer his mistakes against fan favourite Roger Federer at the ATP Finals.

Federer came out on top of the 6-4, 6-3 result and the defeat also ended Djokovic's hopes of pipping Rafael Nadal to the year-end world No 1 ranking.
The Swiss has always been a crowd favourite and it was no different at The O2, but fans took things too far as they applauded some of Djokovic's mistakes.
When asked about the crowd reactions during his post-match press conference, Djokovic played it down.
"I mean, look, it was an important match, and I think every time I face Roger or Rafa anywhere in the world, it's a lot of excitement," he said.
"So it was a full stadium, which was nice to see. It was loud. It was electric. You know, it was a good atmosphere."
However, Croft was far from impressed.
"I felt sad for Novak. Here is a great, great champion. Someone who has achieved so much in the game," she is quoted as saying by Metro.co.uk.
"What does he have to do to get a crowd on his side? He was playing some beautiful tennis and it was just met by polite applause.
"Some of his double faults were being clapped and cheered. It looked to me like he became very subdued and went into his shell after that.
"He couldn't fire himself up. I did feel a tinge of sadness for him because he looked a little lost out here and it can't be easy when you're taking on 20 000 people."
Rusedski also criticised the fans.
"I think it's disrespectful when you're clapping double faults. That's too much," he said.
"I don't mind fans supporting one guy over the other - that's your choice - but there's a certain etiquette you have to have out there.
"That really got into Djokovic's head because he double faulted, some of the crowd applauded and he double faulted again. Then he got broken and from that point on he was always behind in the match.
"He never recovered. He gets too hard a time sometimes."

Text description provided by the architects. This is the rebuilding of the farmhouse built in the hill overlooking the Seto Inland Sea. Before rebuilding, there was the most common farmhouse which has four squarely arranged rooms .
The principal objective of the design is grope of the concrete house which developed from the traditional farmhouse form. The charm of the old farmhouse is a simplicity, a layout of the rooms regarded as structure together, and the component such as eaves and the opening controls house environment.
Because I was going to replace this characteristic with concrete, I thought about bearing wall structure which can make opening to all direction. Specifically, it is the bearing wall structure arranged radially, reinforced " the box " such as storage space.

Miss Universe 2019: Steve Harvey named right costume contest winner, pageant says of apparent flub
by Michelle Ewing, Cox Media Group National Content DeskATLANTA - Steve Harvey can’t catch a break when it comes to Miss Universe.
Years after his gaffe heard 'round the, well, universe, the TV host went viral yet again Sunday when he appeared to announce the wrong winner of the 2019 pageant’s national costume contest, USA Today reported.
“Earlier this week, all the contestants competed in the national costume contest. Here’s a look at the winner, Philippines,” began Harvey, standing in front of an image of Miss Philippines Gazini Ganados.
“This is it right here,” he continued, gesturing toward Miss Malaysia Shweta Sekhon, who had joined him onstage.
She quickly corrected him. “It’s not Philippines; it’s Malaysia,” she said.
″I just read that in the teleprompter," he told Sekhon before turning to the producers. “Y’all gonna quit doing this to me.”
Harvey added: “See, this is what they did to me back in 2015, played me short like that.”
He was referring to his infamous flub from four years ago, when he incorrectly announced that Miss Colombia Ariadna Gutiérrez had won the pageant instead of Miss Philippines Pia Alonzo Wurtzbach, People magazine reported.
But this time, Harvey appeared to be at least somewhat vindicated. Early Monday, the pageant tweeted that he had named the correct winner of this year’s costume contest.

The goal of this design sprint is to further improve and provide TurboTax on-boarding a confidence-building experience while also helping users to further understand TurboTax services.
With the new service of TurboTax Live, their users need a reassuring and informative onboarding process as they often question the credibility of the CPAs and EAs that are providing their personal feedback and assistance for this service.
After identifying the problem and establishing our mission statement, we start to brainstorm a possible solution by writing as many ideas we can in post-it notes then taping it into the wall before we narrow it to several important approaches.
We develop several approaches that can help to provide and ensure a smooth and reliable onboarding process for the TurboTax Live users. Each of these approaches communicates the context, problem, and proposed solution for the stakeholder in order to further narrow down our issues and concepts.
The mission statements then led to our proposed engagement model that addressed the root cause along with building confidence and empowers the users. The main features of this engagement model are adding area(s) of specialization and brief qualifications of the CPAs to give the users more information regarding the experts. Along with that feature, we also added a pop-up chat that can help users to further observe the reviews of their CPAs.
After finalizing our approach to the problem, we made a quick paper prototype that visualizes the significant and interactive elements we hope to achieve in our design.
As one of my first projects that were established out of conventional classroom settings, I find myself learning so much from this day-long event. One of the insights I find interesting is that the design process is very non-linear. Unlike what has always been taught to us during design classes, sometimes the design process itself involves a lot of back and forth between one stage to another to achieve a satisfying end-product. More importantly, I also learn that the documentation of a design workflow is also extremely important as it can further justify our decision when it comes to the design itself. Overall, I'm really proud and satisfied with our end-product as it showcases our knowledge and skill when it comes to user experience and interaction design.
After refining our design, we then present our final design prototype in front of design experts to gain even more insights.
Since this is only a day-long design sprint, we also provided several steps that we need to take in order to finalize this design prototype. These directions include:


Ohio Catholic school announces mandatory random drug testing for all students
by Paulina DedajA Catholic high school in Ohio announced this week that it will begin conducting random drug tests in January to help enforce a new policy banning illicit drugs and nicotine.
Administrators at Stephen T. Badin High School in Hamilton, 30 miles north of Cincinnati, sent a letter home to parents Tuesday informing them of the “aggressive” initiative, aimed at shielding at students who may feel “pressured into experimenting with drugs”.
OFF-DUTY NYPD COP, FDNY MEMBER AMONG 2 CRITICALLY INJURED, IN HORROR EARLY MORNING CRASH
“All students are capable of making mistakes and it is our job to ensure that students learn from them and grow through the process with the support and guidance of their family and the leadership of the school,” the letter states.
The move has sparked a debate over the rights of schools, public or private, to conduct drug tests on students.
Under the new policy, all students will be subject to random testing, at least once a year, in order to maintain their enrollment status.
“There is no maximum number of times a student may be tested,” administrators said.
The letter continued: “Attendance at Badin High School is not a right, but a privilege in which students and parents/guardians are to act in a way that supports the health, safety and well-being of all students.”
AUSTRALIAN POLICE FIND $210M WORTH OF METH HIDDEN INSIDE SRIRACHA BOTTLES
The school will use a third party to test for any “controlled substances, alcohol, nicotine or other unsafe substances/paraphernalia” while on school property or any school related activity. They will also use drug-sniffing dogs to further ensure a “drug-free environment.”
The school offered several guidelines in the event that any student tests positive, with a first offense resulting in family notification and a five-day suspension and a third offense resulting in expulsion.
If students are caught selling any of the named contraband, the administration said that police would be notified.
The new policy also takes aim at the growing use of “vaping products” among teens.

“Vaping products are illegal on school property and are considered a violation of school policy. Due to the increased usage of vapor products in the teen population across the country, we are making our policy clear so that all students and parents understand the ramifications of having or using a vapor product at school, on school grounds or at any school-related function (event),” officials said.
Any refusal to participate in the mandatory tests will be considered a positive result.

htmlTagsTemplate.py
This module uses the names
clients
and title
, they are provided as keyword arguments in the
function Include()
- authenticationTest.pih
- Shows how to use the authentication function, with a simple test function ; the values
to enter are "holden" and "caulfield"
- redirect.py
- Redirection to another URL (in this particular case, my website about Breton songs...)
- scriptErrorTest.pih
- A script with a volontary error, to show how Karrigell prints error messages.
The "Debug" button gives access to the debugger, which shows the script source code and
allows to see the state of variables when the error occured. See also
other errors
- scriptEndTest.py
- A script with a SCRIPT_END exception which allows script interruption before a line
which causes an error
- tabsDemo.pih
- Shows a menu with horizontal tabs
- sessionTestForm.htm
- An HTML form whose data are stored using the session mechanism. Validating data causes a
call to the script
sessionTestBegin.pih
which initializes the session object from form fields. The
following script, sessionTestFollow.pih
shows that data are indeed retrieved through this object
- thisTest.pih
- Shows the attributes of the object
THIS
- requestHandlerTest.pih
- Shows the attributes of the object
REQUEST_HANDLER
- importTest.hip
- This script only imports another one,
importTest.py
and prints a value from this imported script. If the reload_modules
option has been set to 1 in the initialization file (Karrigell.ini
), when the value is changed in importTest.py (by editing the file in a text editor) then if you reload importTest.pih the value also changed. If reload_modules
is not set, the change has no effect
This avoids having to restart the server every time an imported file is changed

This directory contains the necessary tools to install an instance of the microservice demo application on AWS ECS.
curl -sSL https://get.docker.com/ | sh
apt-get update && apt-get install -yq jq python-pip curl unzip build-essential python-dev
pip install awscli
By clicking “Launch Stack” button above, you will get redirected to AWS CloudFormation console. You will be asked to set cluster size (Scale
) and instance type (EcsInstanceType
).
To use CLI, you also need to have the AWS CLI set up and configured.
Other required packages are: jq docker
./deploy/aws-ecs/msdemo-cli build
You can optionally add a Weave Cloud token to the command as
./deploy/aws-ecs/msdemo-cli build myweavetoken
Deployments may take a few minutes to complete.
To track the deploy status you can run:
./deploy/aws-ecs/msdemo-cli status
Once it’s done, it will print the URL for the demo frontend, as well as the URL for the Weave Scope instance that can be used to visualize the containers and their connections.
To ensure that the application is running properly, you could perform some load testing on it using the load-test container. This will send some traffic to the application and generate a report at the end:
./deploy/aws-ecs/msdemo-cli loadtest
Zipkin is part of the deployment and has been written into some of the services. While the system is up you can view the traces. To get the endpoint for Zipkin you can run
./deploy/aws-ecs/msdemo dns
Currently orders provide the most comprehensive traces.


Table of Contents
Overview
This module adds a function compliance_map()
to the Puppet
language. The compliance_map()
function provides the ability
for users to compare their in-scope class parameters against a set of
compliant parameters, either in Hiera or at the global scope.
Users may also provide custom inline policy documentation and mapping
documentation.
The goal of this module is to make it easier for users to both detect, and report on, deviations from a given policy inside their Puppet codebase.
Module Description
This module provides the function compliance_map()
and a
compliance_markup
class for including the functionality into
your stack at the global level.
A utility for converting your old compliance_map()
Hiera data
has also been included in the utils
directory.
Upgrading
A utility script, compliance_map_migrate
has been included in
the utils
directory of the module to upgrade your old
compliance data to newer formats.
At minimum, you must pass to the script a compliance profile to migrate, the version of the API it was compatible with, and the version you wish to migrate it to. For instance, to upgrade a compliance map from API 0.0.1 to 1.0.0:
ruby compliance_map_migrate -i
/etc/puppetlabs/code/environments/simp/hieradata/compliance_profiles/nist_800_53_rev4.yaml
-s 0.0.1 -d 1.0.0
Please validate that the migrated YAML files work as expected prior to deploying them into production.
Reporting
What compliance_markup affects
By default, the compliance_map()
function creates a set of
reports, one per node, on your Puppet Server at
/opt/puppetlabs/server/data/puppetserver/simp/compliance_reports/<fqdn>
.
You may optionally enable the creation of a File
resource on
each of your clients if you wish to have changes in this data automatically
exported into PuppetDB
.
Usage
The compliance_map()
function provides a mechanism for mapping
compliance data to settings in Puppet and should be globally activated by
including
the compliance_markup
class.
It is primarily designed for use in classes to validate that parameters are properly set but may also be used to perform a full compliance report against multiple profiles across your code base at compile time.
When the compliance_markup
class is included, the parameters
in all in-scope classes and defined types will be evaluated against top
level parameters, lookup()
values, or Hiera data, in that
order.
The variable space against which the parameters will be evaluated must be structured as the following hash:
compliance_map :
<compliance_profile> :
<class_name>::<parameter> :
'identifiers' :
- 'ID String'
'value' : 'Compliant Value'
'notes' : 'Optional Notes'
For instance, if you were mapping to NIST 800-53
in the
SSH
class, you would use something like the following:
compliance_map :
nist_800_53 :
ssh::permit_root_login :
'identifiers' :
- 'CCE-1234'
'value' : false
Alternatively, you may use the compliance_map()
function to
add compliance data to your modules outside of a parameter mapping. This is
useful if you have more advanced logic that is required to meet a
particular internal requirement.
NOTE: The parser does not know what line number and, possibly, what file the function is being called from based on the version of the Puppet parser being used.
The following parameters may be used to add your own compliance data:
:compliance_profile => 'A String, or Array, that denotes the compliance
profile(s) to which you are mapping.'
:identifiers => 'An array of identifiers for the policy to which you
are mapping.'
:notes => 'An *optional* String that allows for arbitrary notes to
include in the compliance report'
Report Format
The compliance report is formatted as follows (YAML Representation):
---
# The API version of the report
version: "1.0.1"
fqdn: "my.system.fqdn"
hostname: "my"
ipaddress: "<IP_ADDRESS>"

Options
The compliance_markup
class may take a number of options which
must be passed as a Hash
.
report_types
Default: [ 'non_compliant',
'unknown_parameters', 'custom_entries' ]
A String, or Array that denotes which types of reports should be generated.
Valid Types: * full: The full report, with all other types included. * non_compliant: Items that differ from the reference will be reported. * compliant: Compliant items will be reported. * unknown_resources: Reference resources without a system value will be reported. * unknown_parameters: Reference parameters without a system value will be reported. * custom_entries: Any one-off custom calls to compliance_map will be reported.
site_data
Default: None
A valid Hash that will be converted as passed and emitted into your node compliance report.
This can be used to add site-specific or other information to the report that may be useful for post-processing.
client_report
Default: false
A Boolean which, if set, will place a copy of the report on the client itself. This will ensure that PuppetDB will have a copy of the report for later processing.
server_report
Default: true
A Boolean which, if set, will store a copy of the report on the Server.
server_report_dir
Default: Puppet[:vardir]/simp/compliance_reports
An Absolute Path that specifies the location on
server_report_dir
Default: Puppet[:vardir]/simp/compliance_reports
An Absolute Path that specifies the location on the server where the reports should be stored.
A directory will be created for each FQDN that has a report.
catalog_to_compliance_map
Default: false
A Boolean which, if set, will dump a compatible compliance_map of all resources and defines that are in the current catalog.
This will be written to server_report_dir/<client_fqdn>
as catalog_compliance_map
. Old versions will be overwritten.
NOTE: This is an experimental feature and subject to change without notice.

Enforcement
This module also contains an experimental Hiera backend that can be used to enforce compliance profile settings on any module when it is included. It uses the compliance_markup::enforcement array to determine the profiles to use, and which profiles take priority.
Both a legacy v3 backend, and a modern Hiera v5 backend have been provided. It is highly recommended to use the Hiera v5 backend if the puppet agent on your puppetservers are 4.9 or higher.

Configuring profiles to enforce
To enforce disa stig + nist, with disa stig compliance settings taking priority, add the following to your hiera data files. This will work like any hiera setting, so you can set enforcement based on any factor, including host, hostgroup, kernel or specfic os version.

compliance_markup::enforcement: [ 'disa_stig', 'nist_800_53_rev4' ]
Limitations
Depending on the version of Puppet being used, the
compliance_map()
function may not be able to precisely
determine where the function has been called and a best guess may be
provided.
Development

class TextDrawer(AbstractCairoDrawer):
Class that draws text on a Cairo context.
This class supports multi-line text unlike the original Cairo text drawing methods.
| Method | __init__ |
Constructs a new instance that will draw the given text on the given Cairo context . |
| Method | draw |
Draws the text in the current bounding box of the drawer. |
| Method | draw |
Draws the text by setting up an appropriate path on the Cairo context and filling it. x and y denote the coordinates where the drawing should start. If they are both None, the current position of the context will be used. |
| Method | get |
Calculates the layout of the current text. x and y denote the coordinates where the drawing should start. If they are both None, the current position of the context will be used. |
| Method | text |
Sets the text that will be drawn. |
| Method | text |
Returns the X-bearing, Y-bearing, width, height, X-advance and Y-advance of the text. |

Inherited from AbstractCairoDrawer
:
| Method | bbox |
Sets the bounding box of the drawing area where this drawer will draw. |
| Instance Variable | context |
Undocumented |
| Property | bbox |
The bounding box of the drawing area where this drawer will draw. |
| Method | _mark |
Marks the given point with a small circle on the canvas. Used primarily for debugging purposes. |
| Instance Variable | _bbox |
Undocumented |
Draws the text in the current bounding box of the drawer.
Since the class itself is an instance of AbstractCairoDrawer
, it
has an attribute named bbox which will be used as a bounding
box.
- @param wrap: whether to allow re-wrapping of the text if it does not
- fit within the bounding box horizontally.
Draws the text by setting up an appropriate path on the Cairo
context and filling it. x
and y
denote the coordinates where the
drawing should start. If they are both None, the current position
of the context will be used.
Vertical alignment settings are not taken into account in this method as the text is not drawn within a box.
- @param x: The X coordinate of the reference point where the layout should
- start.
- @param y: The Y coordinate of the reference point where the layout should
- start.
- @param width: The width of the box in which the text will be fitted. It
- matters only when the text is right-aligned or centered. The text
will overflow the box if any of the lines is longer than the box
width and
wrap
is False. - @param wrap: whether to allow re-wrapping of the text if it does not
- fit within the given width.
Calculates the layout of the current text. x
and y
denote the
coordinates where the drawing should start. If they are both None,
the current position of the context will be used.
Vertical alignment settings are not taken into account in this method as the text is not drawn within a box.
- @param x: The X coordinate of the reference point where the layout should
- start.
- @param y: The Y coordinate of the reference point where the layout should
- start.
- @param width: The width of the box in which the text will be fitted. It
- matters only when the text is right-aligned or centered. The text
will overflow the box if any of the lines is longer than the box
width and
wrap
is False. - @param wrap: whether to allow re-wrapping of the text if it does not
- fit within the given width.
- @return: a list consisting of (x, y, line) tuples where x and
- y refer to reference points on the Cairo canvas and line refers to the corresponding text that should be plotted there.
Sets the text that will be drawn.
If text
is None, it will be mapped to an empty string; otherwise,
it will be converted to a string.
Returns the X-bearing, Y-bearing, width, height, X-advance and Y-advance of the text.
For multi-line text, the X-bearing and Y-bearing correspond to the first line, while the X-advance is extracted from the last line. and the Y-advance is the sum of all the Y-advances. The width and height correspond to the entire bounding box of the text.
Iterates over the label line by line and returns a tuple containing the folloing for each line: the line itself, the width of the line and the X-bearing of the line.
Iterates over the label line by line and returns a tuple containing the folloing for each line: the line itself, the width of the line and the X-bearing of the line.
The difference between this method and _iterlines()
is that this
method is allowed to re-wrap the line if necessary.
- @param width: The width of the box in which the text will be fitted.
- Lines will be wrapped if they are wider than this width.


close(
X)
closes the stream corresponding to X.
If X is a stream object, and if the corresponding stream is
open, it will be closed; otherwise, close/1
succeeds
immediately, taking no action.
If X is a file specification, the corresponding
stream will be closed. It is only closed if the file was opened by
see/1
or tell/1
. In the example
see(foo), ... close(foo)
foo will be closed. However, in the example
open(foo, read, S), ... close(foo)
an exception will be raised and foo will not be closed.
told/0
closes the current output stream. The current output stream is
then set to be user_output
; that is, the user's terminal.
seen/0

Boffins uncover 5G flaws that could enable real-time location tracking
Awww G
by Roland Moore-ColyerSECURITY FLAWS IN 5G could let cyber creeps stalk your real-time location, according to security boffins from Purdue University and the University of Iowa.
They found that some 11 flaws exist in the 5G protocol that could enable hackers to spoof emergency alerts or secretly disconnect a phone from a network, as well as track users' real-time locations.
And there's a kicker, as some of the flaws could also be exploited on existing 4G networks.
The vulnerabilities take a bit of wrangling to exploit. For example, an attacker would need to create a malicious radio base station to carry out attacks. And the researchers built a tool called 5GReasoner to find and exploit the vulnerabilities.
To track real-time location, the researchers had to obtain the new and old temporary network identifiers of a target's phone in order to discover the location paging occasion and thus extrapolate a person's real-time location.
So exploiting them might be a bit out of the reach of your garden variety hacker. Though the researchers noted that anyone with a practical knowledge of 4G and 5G networks, as well as access to a low cost software-defined radio, could potentially exploit the flaws. Best keep an eye on any telecoms engineer mates you have with a dodgy look on their mugs.
Regardless of how easy they may be to exploit, the potential for cyber deviants to able to stalk someone or send out fake emergency alerts - think of the kind that had Hawaiians spooked that they were under imminent ballistic missile attack last year - is rather concerning.
The clever folks notified telecom network worldwide trade body GSM Association of new vulnerabilities they found. But the GSMA judged the threat of such vulnerabilities to be "null or low-impact", and its given no indication of if and when the flaws will be fixed.
Maybe Apple's move to wait until at least 2020 before coming up with a 5G iPhone seems sensible, given it doesn't seem as secure as it was once made out to be. µ

URA frustrates KCCA
URA's quest to cut the gap to league leaders Vipers ran into headwinds on Wednesday as they were held at home by plucky URA FC. The Tax Collectors took the lead through Ashraf Mandela in the 8th minute before Alan Okello restored parity in the 57th minutes. The draw leaves KCCA 11 points off the top of the table with four games in hand.
Kickboxing talent search launched
Kickboxer Moses Golola was on hand to launch the Unaweza Extra Kickboxing Talent Search & Exhibition fight which will be held on November 29 at Rock Gardens in Kampala.
Four more picked for Abu Dhabi F1 race
Four more winners from the City Tyres and Pirelli Formula One promotion draw were drawn to join James Bond Kunobere, Musa Osman Rukundo, George Mutebe and Simon Ssekankya for the all-expense paid trip.
Like has been the trend, the winners will enjoy VIP treatment from the beginning to the end. From tickets in the VIP lounge at the Yas Marina and staying at the Grand Hyatt Hotel over the four days and five night’s trip, the winners will have a memorable trip that they will wind up with a desert challenge experience.

2020 Mercedes-Benz GLA teased
The latest compact Mercedes-Benz will be revealed on December 11 as part of the brand's first ever 'purely digital world premiere'.
by Scott Collie- shares
Mercedes-Benz will continue the rollout of compact cars based on its MFA II platform with the December 11 reveal of its new GLA.
At the launch of the new A-Class, the three-pointed star promised at least eight variants based on the same chassis. So far, we've seen seven: the A-Class hatch, sedan and LWB sedan, the CLA coupe and Shooting Brake, and the B-Class and GLB.
That will make the GLA the eighth model on the MFA II platform, essentially completing the set.
When it launches, the GLA will go head-to-head with the Audi Q2/3, BMW X1/2, and the popular Volvo XC40. It's slated to arrive in Australia during the third quarter of 2020.
Based on our prototype drive, the new GLA will have a more upright profile than before as Mercedes looks to turn it from a hatchback on stilts into a proper SUV.
It's almost 20mm shorter than the first-generation car, but has a longer wheelbase for improved interior space.
The cabin will mimic that of the A-Class hatchback, which means dual-screen MBUX infotainment and a flashy ambient lighting system.
The standard engines for the new GLA mirror those of the other recent new Mercedes-Benz compact models.
They include a 1.3-litre and two 2.0-litre turbo petrol units with 120kW, 140kW and 165kW respectively as well as a 1.5-litre turbo-diesel with 85kW and a pair of 2.0-litre turbo-diesels with 110kW and 140kW.
Stay tuned for more on the GLA in the lead-up to its launch.

Explore options
Generate genuine alternate solutions to your business problem – including innovative approaches that may not be readily apparent.
Play description
Identify potential solutions that could address the business problem. There are many methods you can use for developing options, such as brainstorming or scenario planning. You might conduct a design sprint or hackathon to quickly prototype potential solutions. Each option needs to be viable and achievable, and meaningfully different from the other options you might be presenting. It is unhelpful to propose options that you cannot practically implement— due to limitations in your organisation or in your country’s strategic context, such as funding constraints or government policy.
Make sure you understand and can describe the current service. This is your baseline. It provides the basis from which you can measure the advantages, disadvantages, and costs of other options you consider. It is also your ‘No change’ option.
Key activities
Define your baseline
This is the ‘No Change’ option. It provides the basis from which you can measure the advantages, disadvantages, and costs of other options. It may be that the most sensible solution, at least for the time being, is not to make a major change.
Identify feasible options
Try to identify all the options that could achieve the desired outcomes in the current context. Consider any constraints, such as policy or technology, that might limit what options are practically feasible and achievable.
Hold workshops where stakeholders can collaborate to solve problems and share perspectives. You might like to think about options in terms of changes to people, process and technology.
Analyse and compare each option
Establish the criteria against which you will evaluate the options. These should suit the needs of your organisation and government. Your analysis should include a comparison of costs, benefits and risks as a minimum. Refer to Define options for further detail.
Align options to outcomes
Assess each option against the desired outcomes to identify strengths and weaknesses. It is important to note that different options may deliver different measurable benefits against the proposed outcomes.
Questions to consider
- What are all the possible options?
- Is each option a genuine and viable solution to the business problem?
- Have you agreed the criteria you will use to assess each option?
- Have you considered options ranging from minimal technology upgrades to more innovative digital and ICT solutions? This includes those options that may challenge your current ICT planning and service delivery approaches.
- Have you considered the policy and regulatory implications of each option?
- How will each option affect identified stakeholder groups?
- What are the costs and benefits of delivering each option?
- What are the likely consequences of delivering each option?
- Have you considered all the costs, benefits and risks associated with the business case across the lifecycle of the investment (financial and non-financial)?
- How do the options align to your government objectives and priorities?

European defense projects need single export license: Leonardo CEO
European defense programs should be issued with a single weapons export license so policy changes of an individual state do not affect the supply chain, the CEO of Italian defense company Leonardo said on Tuesday.
DUBAI: European defense programs should be issued with a single weapons export license so policy changes of an individual state do not affect the supply chain, the CEO of Italian defense company Leonardo said on Tuesday.
Germany imposed a ban on arms exports to Saudi Arabia in 2018 after the killing of Saudi journalist Jamal Khashoggi.
The ban has been criticized by Germany's European allies since it put a question mark over billions of euros of military orders.
These included a 10 billion pound (US$13.27 billion) deal to sell Eurofighter Typhoon jets, built by a consortium of Germany, Britain, Italy and Spain, represented by Airbus , BAE Systems and Leonardo, to Riyadh.
Germany has not formally stopped existing deals, but equipment from other European countries with German parts has been held up.
The ban has highlighted how Europe's highly integrated defense industry supply chain can be disrupted by a single government.
Currently, each European company involved in a joint program must receive an export license from their respective governments. If one government withdraws or does not issue a license an export can be unilaterally blocked.
"We have to work on understanding how to have an export license that could be valid for many countries which are involved in the same program," Alessandro Profumo told Reuters at the Dubai Airshow.
"If there is a program where the value chain is integrated we need, in my opinion, the prime country, that at (under) certain conditions, can be the one who gives the authorization for all the others."
European states are divided on banning weapons sales to Saudi Arabia. Some have banned sales to the country and its ally the United Arab Emirates over their involvement in Yemen.
Others have continued to export and argue decisions like the German ban are damaging to Europe’s defense industry.
Profumo said a single license would be a decision for European governments but said it was an important consideration for the continent's defense industry.
"It's not up to me to define how (it could work)," he said.

The easiest and best way to work with linked data in Solid is to use a library called rdflib. Rdflib is a general toolbox for doing most things for linked data. It can store data, parse and serialize data into various formats, and keep track of changes to the data coming from the app or from the server.
Here are some basic vocabulary terms we'll be using throughout this document.
Typically people define rdflib in your module as $rdf, so that you an easily cut and paste code between projects and examples here, without confusion.
Installation steps (using npm):
npm install rdflib --save
and then in your code, you will need the following line as well:
const $rdf = require(‘rdflib’)
Suppose we have a store, and we set up a person and their profile. Their webid is the URI 'https://example.com/alice/card#me', which is, if you like, a local variable ‘me’ within the the file 'https://example.com/alice/card'.
There are two ways of creating a store:
const store = new $rdf.IndexedFormula
and the shortcut:
const store = $rdf.graph();
Let's set up a variable for the person of interest, and one for their profile document. Note that the URIs for abstract things in RDF have a # and a local id, just like anchors in HTML. The NamedNode method doc() generates a Named Node for the document.
const me = store.sym('https://example.com/alice/card#me');
const profile = me.doc(); //i.e. store.sym(''https://example.com/alice/card#me')
We are going to be using the VCARD terms, and so we set up a Namespace object to which generates the right predicate URIs for each term.
const VCARD = new $rdf.Namespace(‘http://www.w3.org/2006/vcard/ns#‘);
If we don’t know which vocabulary to use, various groups have their favorite lists. One is the collection of RDF namespaces in Solid projects.
We add a name to the store as though it was stored in the profile
store.add(me, VCARD(‘fn’), “John Bloggs”, profile);
The third parameter, the object, is formally an RDF Term, here it would be a Literal. But you can give a string like “John Bloggs”, and rdflib will generate the right internal object. It will do that with strings, numbers, Javascript Date objects.
We have some data - one quad - in our store! Let's read it out.
Now to check what name is given to this person specifically in their profile, we do:
let name = store.any(me, VCARD('name'), null, profile);
If you are not concerned which file the data may have come from, then you can omit the last parameter -- in fact the object too as it is a wildcard:
let name = store.any(me, VCARD('name'));
Then you will pull in any name from any file you have loaded.
So we have added triples here to a local store. That has just been using it as an in-memory database. Most of the time in a Solid app, we’ll use it as a way of getting and saving data to the web.
Let’s look at two more local operations. If you have turtle text for some data, you can load it into the store using $rdf.parse:
let text = '<#this> a <#Example> .';
let doc = $rdf.sym(‘’https://example.com/alice/card”);
let store = $rdf.graph();
$rdf.parse(text, store, doc.uri, ‘text/turtle’); // pass base URI
Note that we must specify a document URI, as the store works by keeping track of where each triple belongs.
> store.toNT()
'{<https://example.com/alice/card.ttl#this> <http://www.w3.org/1999/02/22-rdf-syntax-ns#type> <https://example.com/alice/card.ttl#Example> .}'
We can similarly generate a turtle text from the store. Serialize is the function. You pass it the document (as a NamedNode) we are talking about, and it will just select the triples from that document to be output.
console.log($rdf.serialize(doc, store, aclDoc.uri, 'text/turtle'));
If you omit the document parameter to serialize, or pass null, then you will get all the triples in the store. This may, if you have used a Fetcher, possibly metadata which the fetcher has stored about the HTTP requests it made in fetching your documents. Which might be interesting... but not what you were expecting.
The store’s match(s, p, o, d) method allows you to pull out any combination of quads:
let quads = store.match(subject, predicate, object, document);
Any of the parameters can be null (or undefined) as a wildcard, meaning “any”. The quads which are returned are returned as an array Statement objects.
Examples:
|
match() |
gives all the statements in the store |
|
match(null, null, null, doc) |
gives all the statements in the document |
|
match(me, null, null, me.doc()) |
gives all the statements in my profile where I am the subject |
|
match(null, null, me, me.doc()) |
gives all the statements in my profile where I am the object |
|
match(null, LDP(‘contains’)) |
gives all the statements whose predicate is ldp:contains |
Once you have a set of statements, you typically want to look at the properties of the statement.
|
subject |
The Node of the subject |
|
predicate |
The NamedNode of the predicate |
|
object |
The Node of the subject |
|
why |
The NamedNode of the document |
The last property is called why because it tells us why we should believe it. In a simple linked data system this is a document we have read. In a more complex system this could point to an inference step. It can also be a special object put in by the Fetcher to store the results of its HTTP operations on the web.
So to find out all the document which mention an old email address as the object of any statement
let oldEmail =<EMAIL_ADDRESS>let outOfDate = store.match(null, null, oldEmail, null).map(st => st.why);
Note how we pull in all the statements and then just keep the ‘why’ parts.
So to find out all the document which mention Alice as the subject or object of any statement
let mentions = store.match(alice, null, null, null).concat(store.match(null, null, alice, null)).map(st => st.why);
Note also while we are here the handy
let aboutAlice = store.connectedStatements(alice, alice.doc())
which pulls in the statements which mention Alice, plus those which mention connected blank nodes, which could include things like the structure of Alice's address, for example.
Suppose we have loaded a bunch of LDP folders and we want to pull out all the pairs of files where one is inside the other.
store.match(null, LDP(‘contains’)).forEach(st => {
console.log(st.subject + ‘ contains + st.object)
});
We have introduced you to match() after the methods any() and each() because most of the time when you are programming we find those are actually more convenient than using match.
You can make a new statement using:
let st = new $rdf.Statement(me, FOAF(‘name’), “Joe Bloggs”, me.doc());
or if that's too verbose, you can use a shortcut provided:
let st = $rdf.st(me, FOAF(‘name’), “Joe Bloggs”, me.doc());
The "st" shortcut exists because you can pass arrays of statements to be deleted or inserted to the UpdateManager's "update()" function as a convenient way of making small changes to the web of data.
But before we get into using the UpdateManager, let's look at the Fetcher, which is your first level of connection to the web.
The Fetcher is a "helper object" which you can attach to a store to allow it to connect to the read-write web of data. The Fetcher handles the HTTP requests, understands MIME types and different formats. It uses the 4th column of the quadstore to track where each triple came from. It can parse data from the net (or elsewhere) and put it in the store. It can generate pretty-printed formatted data from the store, the whole store, or the data corresponding to one data document out there.
Let's set up a store as before.
const store = $rdf.graph();
const me = store.sym('https://example.com/alice/card#me');
const profile = me.doc() // i.e. store.sym(''https://example.com/alice/card#me');
const VCARD = new $rdf.Namespace(‘http://www.w3.org/2006/vcard/ns#‘);
This time, we'll also make a Fetcher for the store. The Fetcher is a helper object which allows you to transfer data to and from the web of data.
const fetcher =new $rdf.Fetcher(store);
Now let's load the document we have been talking about.
fetcher.load(profile).then(response => {
let name = store.any(me, VCARD(‘fn’));
console.log(`Loaded {$name || ‘wot no name?’}`);
}, err => {
console.log(“Load failed “ + err);
});
Typically when dealing with people, a name and an avatar is useful in the user interface. Let's pick up the picture too, but also make the code a little more robust against people having profiles written using different terms.
const FOAF = $rdf.Namespace('http://xmlns.com/foaf/0.1/');
This way, we can try using this namespace if there is no VCARD name.
let name = store.any(me, VCARD(‘fn’)) || store.any(me, FOAF(‘name’));
let picture = store.any(me, VCARD(‘hasPhoto’)) || store.any(me, FOAF(image));
Or we can track all the names we find instead. The function "each()" returns an array of any field it finds a value for.
let names = store.each(me, VCARD(‘fn’)).concat(store.each(me, FOAF(‘name’)));
Let’s build a little card for someone and set it to get a picture from the net when it can. Let’s use the raw DOM as for the sake of an example -- you translate this into the equivalent in your favorite UI framework.
const store = $rdf.graph();
const fetcher = new $rdf.Fetcher(store);
const me = store.sym('https://example.com/alice/card#me')
const VCARD = new $rdf.Namespace(‘http://www.w3.org/2006/vcard/ns#‘);
const FOAF = $rdf.Namespace('http://xmlns.com/foaf/0.1/');
function cardFor (person) {
let div = document.createElement(div);
div.outerHTML = `

???

`;
let image = div.children[0];
let span = div.children[1];
store.load(person).then( response => {
let name = store.any(person, VCARD(‘fn’));
if (name) {
label.textContent = name.value; // name is a Literal object
}
let pic = store.any(person, VCARD(‘hasPhoto’));
if (pic) {
image.setAttribute(‘src’, pic.uri); // pic is a NamedNode
}
});
return div;
}
Then inside of our web application, we could run the following commands:
div.appendChild(card(me)); // My card
fetcher.load(me.doc).then(resp -> {
store.each(me, FOAF(‘friend’)).forEach(friend => div.appendChild(card(friend)));
});
This will pull in the user’s profile to make the picture and name for my own card. Then we explicitly pull it in again to find the list of friends. This is reasonable as the fetcher’s `load` method really means “load if you haven’t already” so continues immediately if it has already been fetched. It’s wise to explicitly load the things you need and let the system track what has already been loaded.
Then for each of the friends it will load their profile to fill in the name and picture of the friend.
Tip: if you are doing this in the Solid world it is good to make any representation of a thing draggable with the URI of the thing as the dragged URI. That means users of your UI will be able to drag say, people from your window into another solid app, to say add them to a group, give them access to things, and so on. Similarly, if your window real estate would be a logical place for users to drop other things or people, make it a drag target. For devices with drag and drop anyway.
Everything in RDF is a thing. We store data about all things in the same sort of way, just using different vocabulary. Suppose you want to list the content of the folder in someone’s solid space. It is very like listing their friends. The namespace for the contents of folders is LDP. So..
const LDP = $rdf.Namespace(‘http://www.w3.org/ns/ldp#>’);
let folder = $rdf.sym(‘https://alice.example.com/Public/’); // NOTE: Ends in a slash
fetcher.load(folder).then(() => {
let files = store.any(folder, LDP(‘contains’));
files.forEach(file) {
console.log(‘ contains ‘ + file);
}
});
The Solid pods give you a bit of metadata about each contained file, including size and type. For example we can look at the RDF type ldp:Container to see when we can list something as a subfolder:
function list(folder, indent) {
indent = indent || ‘’;
fetcher.load(folder).then(() => {
let files = store.any(folder, LDP(‘contains’));
files.forEach(file) {
console.log(indent + folder + ‘ contains ‘ + file);
if (store.holds(file, RDF(‘type’), LDP(‘Container’)) {
list(file, indent + ‘ ‘);
}
}
});
}
list(rdf.sym(‘https://alice.example.com/Public/’));
The results will come asynchronously. If we were building a UI, each would get slotted into the right place.
The UpdateManager is another helper object for the store. Just as the Fetcher allows the store to read and write resources from the web, generally a resource (file) at a time, the UpdateManager object allows the store to send small changes to the data web. It also allows the web app to subscribe to a stream of changes that other people have made, and so keep all places where the data is displayed in sync.
const store = $rdf.graph() const fetcher = new $rdf.Fetcher(store) const updater = new $rdf.UpdateManager(store) ... function setName(person, name, doc) { let ins = $rdf.st(person, VCARD('fn'), name, doc) let del = [] updater.update(del, ins, (uri, ok, message) => { if (ok) console.log('Name changed to '+ name) else alert(message) }) }
The first parameter to update() is the array of statements to be deleted. If it is empty then update() just adds data to the store. (Note for this the user only needs Append privileges, not full Write). The second parameter to update() is the array of statements to be deleted.
function modifyName(person, name, doc) { let ins = $rdf.st(person, VCARD('fn'), name, doc) let del = store.statementsMatching(person, VCARD('fn'), null, doc) // null is wildcard updater.update(del, ins, (uri, ok, message, response) => { if (ok) console.log('Name changed to '+ name) else alert(message) }) }
So in this second case, the function will first find any statements which give the name of the person. It then asked update to in one operation remove the old statements (quads) from the store, and add the new one.
Note that update operation (which does a PATCH operation) is specified by solid to be atomic, in that it will either complete both deletion and insertion, or it will fail and do nothing. If the server is not able to delete the statements, for example because someone else has just deleted them first, then the update must fail with a 409 conflict. In that case, the web app will typically beep or turn pink and back out the user's attempted change in the UI.
To delete triples, or any combination of them, from a resource, use the UpdateManager above. If you want to delete whole resources, then you use the HTTP DELETE method.
store.fetcher.webOperation('DELETE', doc.uri).then(...)
Like in Unix, you can't (currently, 2018) delete a folder unless it is empty. So if you want to, you have to delete everything in it first. Here is your rm -r function to complete this little guide.
function deleteRecursive (store, folder) { return new Promise(function (resolve, reject) { store.fetcher.load(folder).then(function () { let promises = store.each(folder, ns.ldp('contains')).map(file => { if (store.holds(file, ns.rdf('type'), ns.ldp('BasicContainer'))) { return deleteRecursive(kb, file) } else { console.log('deleteRecursive file: ' + file) if (!confirm(' Really DELETE File ' + file)) { throw new Error('User aborted delete file') } return store.fetcher.webOperation('DELETE', file.uri) } }) console.log('deleteRecursive folder: ' + folder) if (!confirm(' Really DELETE folder ' + folder)) { throw new Error('User aborted delete file') } promises.push(store.fetcher.webOperation('DELETE', folder.uri)) Promise.all(promises).then(res => { resolve() }) }) }) }
Use with care..
Using the UpdateManager above we made an app which sends changes to the data web whenever the UI changes. Let's also make it so the UI changes whenever the data web changes. The function we use is:
updater.addDownstreamChangeListener(doc, refreshFunction)
It will sign up for changes by opening a websocket with the server. When a message comes from the server that the document has changed, it will reload the document into the store. It will deal with you calling it for the same document from different places. It will ignore changes which you have made yourself with updater.update(). So all you have to do is provide a function which will sync changes in the store into the UI.
If the user isn't editing the UI, just looking at it, you can more or less get away with
const div = dom.createElement(div') function refresh () { // Not recommended div.innerHTML = '' store.each(subject, predicate, null, doc).forEach(obj) { div.appendChild(renderOneObject(obj)) } } refresh() updater.addDownstreamChangeListener(doc, refresh)
or words to that effect. This will cause the div to be repainted. That isn't as slick as writing a refresh function which adjusts the UI just deleting old things and inserting new ones. That means the user can happily be looking at or editing one part while other parts change.
mugshotDiv = div.appendChild(dom.createElement('div')) function elementForImage (image) { let img = dom.createElement('img') img.setAttribute('style', 'max-height: 10em; border-radius: 1em; margin: 0.7em;') img.setAttribute('src', image.uri) return img } function syncMugshots () { let images = kb.each(subject, ns.vcard('hasPhoto'), null, doc) images.sort() // arbitrary consistency images = images.slice(0, 5) // max number for the space UI.utils.syncTableToArray(mugshotDiv, images, elementForImage) } syncMugshots() updater.addDownstreamChangeListener(doc, syncMugshots)
This uses a handy function syncTableToArray, which comes with solid-ui, but is include here to be complete. Also, to encourage you to make UI which syncs in both directions, even if it isn't built into the framework you are using. So find a way that rdflib fits naturally with your favorite UI framework, if you have one. See the Inrupt Solid documentation for some hints about using specific frameworks.
function syncTableToArray (table, things, createNewRow) { let foundOne, row, i for (i = 0; i < table.children.length; i++) { row = table.children[i] row.trashMe = true } for (let g = 0; g < things.length; g++) { var thing = things[g] foundOne = false for (i = 0; i
= table.children.length) { table.appendChild(newRow) } else { let ele = table.children[g] table.insertBefore(newRow, ele) } newRow.subject = thing } // if not foundOne } // loop g for (i = 0; i < table.children.length; i++) { row = table.children[i] if (row.trashMe) { table.removeChild(row) } } } // syncTableToArray
We've looked at how to interact directly with the store as a local in-memory triple store, and we have looked at how to load it and save it, web resource at a time. We see how it ina away acts as a local in-memory cache of the big wide web of linked data, allowing a user-interface to keep in sync with the state of the data web. As developers we can now write code which will allow users to explore, create, modify and link together a web of linked data which can grow to encompass more and more domains, different applications.


Static Vs Dynamic
Static Languages
Programming languages that have static typing have to have the variables declared for which type they are.These languages the variables are known at the time of compliling. This allows for the compiler to check and catch bugs early on. For example if you wanted to declare a variable as an integer value you first would need to tell the variable it was going to be an integer then give it a value:
int number1; number1 = 5;
Dynamic Languages
Other languages have dynamic typing which allows you to forgo the declartion of what type of variable it will be. The variable type is interperted during runtime. This allows for the programmer to take out some of the declartion code and be faster. Example:
number 1 = 5;


I like ice cream, friends, and alcohol. I like to play video games, D and D, and watch football, but I don't do any of those things nearly as much as I'd like

Matt Booty on Xbox Game Studios: “This is the tip of the iceberg”
by Steve Wright"We've really got... more games than we know what to do with."
“This is just the tip of the iceberg for us,” Matt Booty, head of Xbox Game Studios, said at X019 this morning.
“We’re going to show you some amazing things today, but before the end of the year we will show you even more games,” Booty said in an address to media. “Then, as we go into 2020, I think you will see one of the most exciting lineups that we’ve had coming from Xbox Game Studios in as long as I can remember.
“I really want you to be on the look out for the games that we’re going to be announcing heading into that stretch,” Booty continued. “It’s really exciting and really for the first time ever we’ve really got in a way more games than we know what to do with in terms of when they’re going to be announced, so feeling really good about that.”
Stay tuned from more from X019.
